Entered in the State Register of Grape Varieties in 1998.
The variety stems from a crossing undertaken at the Vine Research Centre in Bratislava between (Red Traminer x Red-White Veltliner) developed by vine-breeders D. Pospíšilová and O. Korpas.
With higher yields and lower levels of grape ripening the wines will be rather dull and have a bitter finish.
It is of medium growth and when grown in drier soils, the wines become flabby in most harvests. Annual growth is sparse. Resistance to frost and peronospera fungus, however, is good, against oidium and grey rot it is lower. Crop is regular, its must-weight levels are higher, and quickly increase in final ripening stages. This is why it is capable of making wines at the top end of the special-selection category. It requires mainly best vineyard positions where it gives lush and well-balanced wines. With higher yields and lower levels of grape ripening the wines will be rather dull and have a bitter finish.
